To @ZZ whom, it may concern.-

Beit known that LOHARLES NoELL FELIX, a citizen of the United States ofAmerica, and a resident of the city of Cleveland, county of Cuyahoga,and State of Ohio, have invented certain newand useful Improvements inMiter-Boxes, (Case No. 1,) of which the following is a specification.

My invention relates to folding and adjustable miter-boxes, and has forits object the provision of a device of this class ot' simple andcompact construction and embodying advantages not hitherto fullyattained.

rThe device of my invention, by reason of novel features subsequently tobe pointed out, is capable of various uses,which were but imperfectlyattained in initier-boxes of the prior art. 'Ihus in my improved devicethe widest range of adjustment of the miter-cut is permitted, while anydesired type of saw maybe employed therein. My ruiter-box may be verycompactly folded together in order to secure its adjustment or totransport it or pack it away, and with it accurate miter-cuts may bevery rapidlydetermined and made. The structural details by which theseand other advantages are secured will appear by reference to theaccompanying drawings and description, of which drawings- Figure Iillustrates in plan view the preferred form of my improved miter-boxfully expanded or extended and with the bottomboard removed. Fig. II isa front elevation of myimproved device. Fig. III shows a bottom planview of the miter-box in its closed or folded position. Figs. IV and VIare crosssectional views of two forms of the saw guide or support, andFig. V is a detail view illustrating the sectional construction thereof.

In the drawings the same characters of reference are employed toindicate similar parts throughout the several gures.

The front and back frames A B respectively carry the adjustable andstationary supporting-brackets C, C', C", and E,wherein the saw-guidesor upright supports D are mounted to be freely rotatable therein.`Pivotally-mounted sets of connecting-links F, united in quadrilateralform, serve to adj ustably connect the front and back frames, so

that they may be moved toward or away from each other.

A slotted center rod G accommodates the diagonally-united and movableends of the connecting-links F, whereby they are stayed and caused tomove evenly. Two additional sets of connecting-links F', Fig. III, unitethe frames from beneath, serving to stiffen the structure, whilethumb-screws F" serve to clamp the several lever-arms and the centerrod, together with the connected frames A B, in any desired position ofadjustment.

Arms or braces I are screwed to the back frame, in position to supportthe back board J. (Shown in dotted lines, Fig. II.) A suitable bottomboard K of any desired width is placed upon the frames, which supportsthe articles being sawed and also prevents the saw-teeth from strikingthe metal of the frames or guides. By removing one of the screws fromeach of the said braces-the latter may be folded down into the positionshown upon the left of Fig. II for the purpose of packing or carryingthe device.

Upon the back frame are provided the ears B', which may be utilized insecuring it to the work-bench, if desired, in which position thefrontframe may of course be adjusted as desired.

Along the forward face of the front frame extends a longitudinal slot H,in which the entering tongues H of the adjustable sawguide brackets areseated and readily slide, said brackets, it will be seen, being easilysecured in any position of adjustment by means of thumb-screws F"'. Ifdesired, adjustingscales, as l 2 3 and l' 2' 3', may be provided forsetting these brackets for the required miter-cut, with the box expandedand contracted.

The saw-guides preferably are constructed in two similar sections D' D',as shown in Figs. IV to VI, and are riveted together through the stem.As shown in the drawings, the guidingfaces thereof are made ofconverging con- Vex form, so that the saw is engaged only by the centerof said guiding-faces. The support or guide designed for use with sawshaving no set is shown in cross-section, Fig. lV, the device beingformed wholly of metal.

If a saw with any decided set is to be employed, the guide of Fig. VIshould be used, which has tubular supporting- Walls and a softer coreD", as wood, which will not injure the saw-teeth.

With the above exception the entire device preferably is constructed ofmetal, as iron and steel, and accordingly is very durable and notsubject to Wear. The core and sectional saw-guide may be replaced withslight expense when required.

The utilities of myimproved miter-box will now be readily appreciated.When the forward guide is placed in the middle bracket C, the box is setfor a square cut, and to insure this adjustment a small notch andentering lug are provided, respectively, in the frame and on the rearface of the bracket. This feature, quite obviously, could be utilizedfor the various more common miter-cuts; but I prefer to give the otherbrackets the widest range of close adjustment, and accordingly providethem With plain engaging-faces adapted to be clamped at any point on thefront face of frame A.

For miter-cuts substantially greater than forty-five degrees the box isadjusted by loosening the thumb-screws F", removing the bottom board, iftoo Wide, and bringing the front and back frames as near together asrequired, which makes possible a cut (indicated by line L L) closelyapproaching ninety degrees. This Wide capacity of my device may bematerially increased merely by reversing the position of bracket C,which makes it very valuable to certain classes of workmen, aspattern-makers. for adjustment is secured without resorting to the useof a long arc or other cumbersome appliance for adjustably carrying theguide or guides.

The miter-box is very readily set for .any desired cut, since the partto be cut may be marked therefor and placed in the box. The saw Withinits adjustable guides is moved so that its, blade is parallel with themark designating the required miter-cut and the bracket is clamped inposition, after Which the cutis made in the usual manner.

As indicated by Fig. III, the miter-boX may be folded to very smallcompass, both for the purpose of adjustment and for packing ortransporting the box.

Various changes in and utilities of myimproved device Will readily occurto one accustomed to its use; but I believe that my invention has beensufficiently set forth herein in its preferred form, and. Iaccordinglyclaim, with such changes in form, the following:

l. In a device of the class described, the

This increased capacity Grados combination with parts or frames A B, ofcollapsible connecting mechanism adapted to maintain the same parallelin various positions of adjustment with respect to each other, andsaw-guides, as D, adjustable with respect to each other upon the frames,and carried by said frames, substantially as set forth.

2. In a miter-boX, the combination with frames A B, of brackets, as C E,carried thereby, said brackets C being adjustably mounted on frame A,saw guides or supports, as D, rotatably mounted in said brackets, andcollapsible or folding connecting parts permitting the adjustment offrames A B toward and from each other, substantially as set forth.

3. The combination with a miter-box of a saw-guide D comprising twosimilar parts secured together near their lower ends to form a slottedrotatable supporting part or upright having stationary convex engagingfaces and a cylindrical stem, substantially as set forth.

4t. In a device of the class described, the combination with parts orframes A B, of pivoted connecting-links F, adjustably uniting the same,saw-guides, as D, carried upon said frames and relatively adjustablethereon, and means for securing the parts in their positions of adjustment,substantially as set forth.

5. In a folding and adjustable miter-box, the combination with front andback frames A B, of sets of adjustable quadrilaterallyunited links, as FF, connecting the same, saw-guides, as D,. carried by said frames andadjustable thereon, and means for securing the parts in their positionsof adjustment, substantially as set forth.

6. In a folding miter-box, the combination with front and back frames orparts A B, of brackets carried thereby and relatively adjustablethereon, saw-guides mounted in said brackets, sets of connecting-lin ksF F, uniting and permitting the expansion and contraction of the frames,and arms I, adapted to be folded to the plane of the frames,substantially as set forth.

7. In a miter-box, the combination with frames A B, of brackets, as C CE carried thereby, the former being adjustably mounted in frame A, sawguides or supports D adapted to be interchangeably carried in saidbrackets C C', and sets of connecting-links F F adjustably unitingframes A B substantially as and for the purpose set forth.
